[citation needed], Condition characterized by an abnormal bone growth in the middle ear. Grade 3, diffuse confluent cochlear involvement (with or without fenestral involvement). Much of the clinical course is characterized by lucent rather than sclerotic bony changes, so the disease is also known as otospongiosis. 20 terms. However, due to the progressive nature of this condition, use of a hearing aid is palliative at best. [citation needed], In the absence of a pathology, a loud sound (generally greater than 70 dB above threshold) causes the stapedius muscle to contract, reducing the admittance of the middle ear and softening the perceived loudness of the sound. Hearing aids help people who are suffering from conductive deafness, including otosclerosis. The middle ear is the area behind the eardrum and it has tiny bones, the sound waves are amplified by them. The primary form of hearing loss in otosclerosis is conductive hearing loss (CHL) whereby sounds reach the ear drum but are incompletely transferred via the ossicular chain in the middle ear, and thus partly fail to reach the inner ear (cochlea). Also, a conductive pathology will attenuate the test stimuli, resulting in either elevated reflex thresholds or absent reflexes when the stimulus is presented in the affected ear and measured in the other ear. CHL in otosclerosis is caused by two main sites of involvement of the sclerotic (or scar-like) lesions. This can affect one ear or both ears. Hearing aids can be tuned to specific frequency losses. [23] Early attempts at hearing restoration via the simple freeing of the stapes from its sclerotic attachments to the oval window were met with temporary improvement in hearing, but the conductive hearing loss would almost always recur. oto= ear sclerosis= hardening.

A modern variant of this surgery called a stapedotomy, is performed by drilling a small hole in the stapes footplate with a micro-drill or a laser, and the insertion of a piston-like prothesis. (American Joint Committee on Cancer. Usually both ears are affected in otosclerosis but sometimes only one ear is affected. However, medial fixation of the ossicular chain impairs both the inertial and osseotympanic modes of bone conduction, increasing the bone-conduction thresholds between 500 Hz and 4 kHz, and reducing the size of air-bone gaps. This procedure restores continuity of ossicular movement and allows transmission of sound waves from the eardrum to the inner ear. [4][5][6] Ribonucleic acid of the measles virus has been found in stapes footplate in most patients with otosclerosis. Otosclerosis is a condition of the inner ear where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth.This condition affects one of the ossicles (the stapes) resulting in hearing loss, tinnitus, vertigo or a combination of symptoms.
